Reading's country girl (7)
I believe the answer is:
perusal
'reading's' is the definition.
(perusal is a kind of reading)
'country girl' is the wordplay.
'country' becomes 'peru' (Peru is an example).
'girl' becomes 'Sal' (feminine given name).
'peru'+'sal'='PERUSAL'
(Other definitions for perusal that I've seen before include "worth a close look" , "Scanning, reading" , "Careful reading" , "Thorough reading" , "Study or scrutiny" .)
